I To all whom. it mm:

ments in Machines for Perforating citizen. of the United. States of America, re- 0 f spect1vely,sa1d extensions being arranged in Be it known that I, JOHN F. WHrrn, a

siding at N. S. Pittsburg, in. the county 0 -Allegheny and State of Pennsylvania, have invented certain new and-useful Im' rove hect- Mnsie, of which the following is a specification, reference being had therein to the accompanying drawing.

This. invention relates to-a machine for perforating ml'isic sheets and the objects of the invention are to provide positive and reliable means for expeditiously and economically perforating sheets of paper or other suitable material for use in'musical instrumentscoinmonly styled automatic pianos, piano players, and'the like, and to accomplish the above object bya mechanical construction that is simple,-durable, easy to operate, and eflicient for the purposes for which itis intended; v a

. Further objects of the invention are to util-.

ize electrical devices for actuating dies,

and toarr-an e and assemble the c tcrical devices: and t eir pertinent parts in such a mannerjhat they will be accessible and 0ccupy a comparatively small space..

These and such other objectsfas may hereinafter appear are attained by the novel construction, combination, and arra i of parts to be hereinafter specific ly described, and then claim-ed. I

Reference will. now be had to the drawings, wherein v F igume'l is a front elevation of the perforati-ng machine. Fig.2 is a side elevation 'of the same. Fig. 3 is an enlarged cross sectional View of the upper part of themachine, showing the electrical devices. Fig. 4 is an enlarged cross sectional view of a portion of the lower part of the machine, showing the punches. Fig. 5 is a perspective view of a detached electrical device adapted to form part of the machine.

A machine in'a'ecordance with my inventi'on c'omprisestwo frames 1 and 2; the frame ement- I being of a less height than the frame 2. These frames have the upper ends thereof provided with angular extensions 3 and 4 repa'rall'elism and the extension 3 connected to the base 5 of the frame, 1 by a web 6, while the frame 2 is reinforced relatively to the base 7 of said frame by a. web- 8.

9 and mounted uonone on is a belt or sproc et wheel 16), whereby the power. Mounted-upon the opposite. end. of the shaft is a large beveled gear wheel 11 ed upon an an larly disposed shaft. 13,

journaled in a 'earin angular extension 3 an in a bracket 15, carried by the outer side of the frame 1 'to one side of the web 6. The lower end of the shaft 13 is provided' with a beveled pinion l6. meshing'with a large beveled gear wheel 17 mounted upon a shaft 18 j'ournaled in the -wheel 17 is provided with a radia y disposed (pin 20 adapted to actuate a star or toothe wheel 21 mountedupon the end of a shaft 22 journaled in the frames 1 and 2. The shaft 22 adjacent to the toothed wheel 21 is provided with a ratchet Wheel23: and engaging said Wheel is a spring-pressed pawl 24 carried by t-he outer side of the frame 1, said pawl preventing a rearward rotation of heldin engagement with the ratchet wheel by a Hat spring 25 secured to the outer, side of the frame 1'. The shaft 22 extends through the frame 2 and is provided with a small gear wheel 25 meshing with another gear wheel 26'mounted up0n the end of a shaft 27,. jLournaled the frames 1 and 2 above theshaft '22. Mounted upon the shafts 22 and 27 are feed rollers 28 and 29 respectively. I

and a guide plate 31,"the; guide plate being located directly above the die plate'30. The die plate 30 is provided with openings 32 and dies 33, while the guide plate 3.1 is pro- I Journaled in the upper ends of the angw lar extensions 3 and l is a longitudinal shaft of saidshaft Connecting the frames 1 and 2v adjacent to the feed-rollers 28 and 2.9 is a die plate 30 shaft 9 can be driven by a suitable source of meshing-with a small gear wheel 12 mount- 7 14, carried by the frame 1. The-hub: 19 of the lar egear the ratchet wheel. The pawl is normally vided with openings 34 adapted to vertically aline with the openings 32 and with the openings of the dies 33, the openings 34 guiding punches 35 employed for perforating sheets of paper as it is carried between the plates and 31 by the feed rollers 28 and 29.

The confronting sides of the angular extensions 3 and 4 are connected by a longitudinal plat-form 36 and extending upwardly through the ends of said platform upon the inner sides of the extensions 3 and 4 are uides 37 for a reciprocating frame ormemer, comprising a head 38, side bars 39 and end plates 40, these plates being provided in their outer faces with vertical grooves 41 to receive the guides 37 of the angular extensions 3 and 4. The head 38 of the reciprocating frame adjacent to each end thereof is provided with apertured lugs 42 and pivotally connected to said lugs by pins 43 are the depending arms 44 of eccentric rings 45 movably mounted upon eccentrics 46 secured to the shaft 9.

' Upon the platform 36 aremounted a plurality of electrical devices, the devices being arranged in two rows cqrresponding in number to the keys of a plhno. Each de- Vice comprises an electro-magnet- 47 mounted upon a tiltahlc support 48,'said support lnwingdepending oppositely disposed apertured lugs 49 pivotally connected bya pin 50 to apertured bearings 51, carried by the platform 36. 52 of the electro-magnet is a detent 53 having the forward end thereof bent upwardly, as at 54.

Encircling the detent 53 between the base 52 and the forward end thereof is a coiled compression spring 55 adapted to normally retain the forward end of the detent in engagement with a pivoted armature 56 having the upper end thereof pivotally connected by a pin 57 to a forwardly extending lug 58, carried by thenpper edge of the electro-magnet 47. An outward movement of the pivoted'armature 56 is limited by a stop 59, carried by the edge of the tiltable support 48. The tiltable support 48 is normally retained in a horizontal position by a coiled spring 60 arranged between one end of said support and the platform 36,

4 and the tilting of said support is limited by an upright 61, carried by the platform 36, but in the majority of instances it is not nec-- essary to use these uprights. The forward end of the support 48 is provided with depending apertured lugs 62 and pivotally connected to these lugs by a in 63 is the 'ipper end of a connecting ro 64, said rod extending through an opening 65 provided therefor in theplatform 36. The lower end of the connecting rod 64 is connected by a universal coupling or link 66 to the. arm 67 Slidably mounted in the baselever 68 is pivotally supported by a pin 70 extending through the plate (39, said pin also serving to support a similar bell .cra nk lever upon the ,opposite side of the plate. The

bell crank lever is connected by a universal coupling or link 71 to a connecting rod 72 extending downwardly between the frames 1 and 2, and having the lower ends thereof pivotally connected by a pin 73 to an" arm 74 fulcrumed upon a rod 75 connecting the frames 1 and 2 above the guideplateBL The opposite end of the arm 74is looselymounted in the upperbifurcated one of the punches 35.

As heretofore stated, the number of electrical devices corresponds to the keys ofa piano and. they are arranged in two rows. aran inclination to the guide plate 31 whereby the punches 35 can be compactly arranged to punch a narrow strip of aper. The

end 76 of punches are arranged in a sing e row with some of the punches of a greater length than the others, whereby one of the rods 75 can be located in a plane above the other.

The -electro-magnets constituting the electrical devices can be energized from a suitable source of energy, either in connection with electrically connected piano keys or a master sheet, and when the electro-magnets are energized, the pivoted armatures 56 thereof immediately move the detents 53 into the path of theside bars 39 of the reciproeating frame. As the frame is reciprocated through'the medium of theshaft v9 and the eccentrics 46, the side bars 39 will impinge those detcnts thatvare extended through the medium of the electro-magnets 47, and the supports 48 of theenergized electro-magnets will be tilted'to pull upwardly-upon the connecting rod 64, rock the bell crank lever 68, raise the connecting rod -72,,rock the fulcrumed arms 74 and lower the punches 35 with sufficient force toperforate the sheet of paper passing between the plates 30 and 31'.

In Fig. 2 of the drawings I have illustrated in dotted lines a sheet of paper and in Fig. ,7 have shown an enlarged portion of the same, the sheet being designated 77.

As the sheet is carried between the plates- 30 and 31 by the feed. rollers 28 and 29, which are moved through the medium of the mechanism previously described, the punches 35 descend and either provide the paperwith rows of single perforations 78 or communicating perforations 79 corresponding to slots. -A single perforation is accomplished by the reciprocating bar im-- rocating frame to strike the detent.

pinging the detent once, the electro-magnet controlling the movement of the detent. simply being energized for that period of time required for the side bar of the recipo produce communicating perforations the electro-i'nagnet is energized to hold the detent thereof in an extended position until the side bar 39 of the reciprocating frame has engaged the detent a sufficient number of times to produce a slot. For instance the slot designated 79 is equivalent to six single erforations. While the reciprocating frame 15 being reciprocated, the sheet of paper is gradually movedbetween the plates 30 and 31, consequently rows of perforations or slot-s will be produced during the operation of the machine. hen an electro-magnet is deenergized the coiled spring surrounding the forward end of the detent 53 immediately restores the detent to its normal position, also the pivoted armatures 56, and the spring beneath the rear end of the support 48 restores said support to. a horizontal posit-ion. The shafts 18 and 27 can be extended and provided with feed rollers '80 for moving a master sheet, which will control in connection with the suitable source of electrical energy the energizing of the electro-magnets 47. To assist in restoring the fulcrumed arms 74, the punches 35 and the connecting rod 72 to their normal position, the frames 1 and 2 are connected by transverse bars 81 and secured to these bars are flat springs 82 adapted to engage the rear ends of the arms'74, these springs being placed under tension when the punches areplaced in operation, and the tension of the springs restoring the .punchesto their normal position when the bar reciprocates or makes an upward stroke.

' From the. foregoing it will be observed that I have deviseda compact machine embodying -horiz'ontally. arranged punches, an-

gularly' disposed'tiltable electi e-magnet supv ports normally retained'in an inactive position and ada ted to actuate said punches; detents carrie by said supports and adapted to'be shifted by the energizing of said electro-magnets to place said supports in an active position, a reciprocating frame for tilting said supports,-and means for simultaneously operating said frame and moving a sheet of paper beneath said punches. It is by this'combination of elements that a sheet of paper is easily, quickly and accurately punched. 1
